Drill Motor Transmission

[Adam Y.]

I don't really see any reason for using the drill tranny in the future...

Those drill trannys are very very useful and fairly reliable. Though our team had only one problem it only took five minutes to fix. Can you explain your problems in a little bit more depth?

The first problem was with the shifter clips popping out and was easily remedied. The second problem, I think, was caused by the clutch housing separating or shifting slightly away from the gearbox housing and causing the clutch to disengage. At the time, in the rush of the competition, we merely swapped the transmissions for new ones. We figured the little tabs that hold the housings together had broken off. After looking over some of the parts back home, I’m now wondering if the clutch housing just rotated, since it provides all the torque keeping the last ring gear from rotating. (I can’t picture right now whether the mounting hardware grips the clutch housing; we’re using the FIRST provided mounting assembly) If this is the case, then the problem should only occur when running in low (which we do), since the shift ring prevents the clutch housing from rotating when in high.

It sounds like your describing what happened to our team's robot but it wasn't the drill transmission that was causing it. It was the fact that the drill motors did not mesh together correctly.
